Slide 2: 22 September, 2010 gyan agnihotri 2 The Spine Spine - 3 main functions. To protect the spinal cord To allow movement. To support the upper body.
The Structure & Function of the Spine : The Structure & Function of the Spine Provides a flexible connection between the upper and lower half of the body Encloses and protects the spinal cord Is involved in most movements of the trunk and limbs by providing key attachment points for muscles Has a very significant function in weight bearing but only with correct posture Is very prone to injury if used incorrectly
The Human Spine(backbone, spinal column) : 22 September, 2010 gyan agnihotri 4 The Human Spine(backbone, spinal column) Consists of a column of small bones each called a VERTEBRA If numbered 1-33 (starting with 1 nearest the skull): 1-7 are known as “CERVICAL VERTABRAE” 8-19 are known as “THORACIC VERTABRAE”
The Human Spine(backbone, spinal column) : 22 September, 2010 gyan agnihotri 5 The Human Spine(backbone, spinal column) 20-24 are known as “LUMBAR VERTABRAE” 25-30 Fused Vertebrae known as “SACRUM” 30-33 Fused Vertebrae known as “COCCYX”

The Spine : The Spine Each muscle in the back can move 1.25 cm Multiply this movement by 33 vertebrae and this allows us to bend The body is 20mm shorter at the end of the day than at the start
The Spine : 22 September, 2010 gyan agnihotri 8 The Spine Each vertebrae is separated by a gel like substance, the disc. These discs bend and stretch as we move
The Spinal Cord : 22 September, 2010 gyan agnihotri 9 The Spinal Cord The Spine protects the spinal cord. The spinal cord and the nervous system controls all systems in the body. As the cord descends from the brain nerves peel away from the cord at each vertebrae, leading to all other parts of the body. Damage to the cord will result in the blockage of signals from the brain to the area affected.

The Nerves : 22 September, 2010 gyan agnihotri 11 The Nerves
Slipped Disc : 22 September, 2010 gyan agnihotri 12 Slipped Disc A slipped disc is also called a “herniated or prolapsed” disc It is a bulge in the wall of one of the discs between the vertebrae pressing onto the nerve
Slipped Disc : 22 September, 2010 gyan agnihotri 13 Slipped Disc Main symptom is sciatica (pain in legs, back and buttocks) Other damage often occurs at the same time, such as muscles strain and tears Treatment: Minimum stress to the spine Correct posture Time to heal
